This is an excellent bookstore. Although it is primarily Spanish language, there is a wide…read moreselection of English language books, not just the rack of Penguin classics that the 'sadly limited to only English' traveler finds while on the road. There are new interesting paperbacks - the kind of book you read a review of, made a mental note to buy, and then forgot, as well as some really well chosen older titles - AJ Lieblling on boxing, Bruce Chatwin, Finnegan's Barbarian Days. And the eggshells language books aren't entirely segregated off in some corner.
This shop comes up under cafes rather than bookstores, for reasons I cant parse, but i was very happy to wander in. they have a branch in the Reina Sofia.
